Micro Polarization Beamsplitter Cube (PBS)

Micro Optics >>> Micro PBS (Polarization Beamsplitter Cube)

Micro PBS separates a laser beam into two different polarization beams. Micro PBS is generally used in fiber optical communication as the core component of polarizer, polarization beam combiner, and interleaver.

Features
  • Low Polarization Dependent Loss
  • Low Insertion Loss
  • Low PMD
  • Environmentally Stable
Applications
  • Polarization Beam Combiner
  • Raman Amplifier
  • Circulators
  • Interleavers
